Mechanical ventilation nowadays remains the cornerstone in life saving in critically ill patients with and without respiratory failure. However, conclusive evidences show that mechanical ventilation can also cause lung damage, specifically, in terms of ventilator-induced lung injury. Respiratory monitoring encloses a series of physiological and pathophysiological measurements, from basic gas exchange and ventilator wave forms to more sophisticated diaphragm function and lung volume assessments. The progress of respiratory monitoring has always been accompanied by advances in technology. However, how to properly conduct the procedures and correctly interpret the data requires clear definition. The book introduces respiratory monitoring techniques and data analysis, including gas exchange, respiratory mechanics, thoracic imaging, lung volume measurement, and extra-vascular lung water measurement in the initial part. How to interpret the acquired and derived parameters and to illustrate their clinical applications is presented thoroughly. In the following part, the applications of respiratory monitoring in specific diseases and conditions is introduced, including acute respiratory distress syndrome, obstructive pulmonary diseases, patient-ventilator asynchrony, non-invasive ventilation, brain injury with increased intracranial pressure, ventilator-induced diaphragm dysfunction, and weaning from mechanical ventilation. This book is intended primarily for ICU physicians and other practitioners including respiratory therapists, ICU nurses and trainees who come into contact with patients under mechanical ventilation. This book also provides guidance for clinical researchers who take part in respiratory and mechanical ventilation researches.

Weaning from mechanical ventilation. - ArticleEngelhard VH, Guild BC, Helenius A, Terhorst C, Strominger JL.Proc Natl Acad Sci U S A. 1978 Jul;75(7):3230-4.Purified detergent-soluble human histocmpatibility antigens (HLA-A and HLA-B) were reconstituted into phospholipid vesicles by mixing the protein and lipid together in the presence of either octylglucoside (octyl-beta-D-glucopyranoside) or deoxycholate and removing the detergent by dialysis. The resulting preparation consisted of lipid vesicles containing all or most of the added protein. The protein in the vesicles was antigenically active, as demonstrated by specific binding to anti-beta2-microglobulin IgG-Sepharose beads and by specific inhibition of alloantibody and complement-mediated cytotoxicity. Protein incorporated into vesicles at a protein/phospholipid ratio of 1:10 showed an asymmetric distribution of the HLA-A and HLA-B molecules, with virtually all of the antigens oriented facing the external medium. Cleavage experiments with proteases showed that the molecule was attached to the vesicle membrane via the COOH terminus, consistent with its proposed structure in intact cellular plasma membranes. Electron micrographs of the vesicles showed 50-60 A knobs on the outer surface similar to structures observed for other membrane proteins. HLA-A and HLA-B could also be incoporated into vesicles together with Semliki Forest virus membrane proteins. The resulting preparations should be useful in defining the molecular interactions involving HLA-A and HLA-B antigens in the immune response.
